Crisp Tetraploid Contrast for the Canadian Shade Garden

Hans Hansen of Walters Gardens registered Hosta 'American Sweetheart' in 2002 as a tetraploid sport of H. 'Sea Thunder'. The tetraploid status gives it significantly thicker leaf substance and greater garden vigour than its parent. Upright, heart-shaped leaves emerge with a creamy-yellow centre that brightens to a clean white as the season progresses, framed by an extra-wide, dark green margin throughout. At 61 cm (24") tall and 104 cm (41") wide, it forms a bold, vase-shaped mound that anchors shaded borders with striking presence. It grows reliably across Canadian hardiness zones 3–9.

Crisp White Centre with Seasonal Shift: Leaves emerge creamy-yellow and brighten to a clean, stable white by midsummer, creating a sharp halo effect against the saturated dark green margins.
Tetraploid Leaf Substance: Thicker, leathier foliage than standard diploid hostas, offering elite natural resistance to slug damage and outstanding garden durability throughout the Canadian season.
Upright Vase-Shaped Habit: The architectural mound adds vertical interest and allows smaller companion plants to be tucked naturally around its base.
Luminous Shade Presence: The wide white centres act as a natural reflector, brightening the darkest corners of a woodland border or shaded garden bed.
Lavender Summer Flowers: Elegant blooms rise on sturdy upright scapes in mid-to-late summer, adding a soft finishing touch and attracting local pollinators.

Feature	Specification
Size (H × W)	61 cm × 104 cm (24" × 41")
Hardiness Zone	3–9
Colour	Creamy-yellow to white centre with wide dark green margin
Light Requirements	Partial to full shade

Grower's Tip: 'American Sweetheart' handles Canadian winters with ease from Zone 3 through 9, and its tetraploid toughness makes it one of the most reliable white-centred hostas for gardens from Winnipeg, MB — where winters are legendary — all the way to St. John's, NL. We grow every division at our nursery in Bécancour, QC, monitoring the creamy-to-white centre transition and wide green margins before every plant ships. Our True to Type standard means you receive the authentic 'American Sweetheart', confirmed before it leaves Bécancour.
